1) Location is PERFECT; It's just right next to Terminal 21 ; 1-2 mins walk to Asoke BTS station. There're also many restaurants, bars, massage shops, few supermarket nearby!
2) The apartment is really spacious and comfy, and nicely cleaned. You'll find everything that fulfil your basic needs.
3) The host, Gerd, is helpful with rather quick response.
All in all I'll definitely recommend this place. I say it'd be a perfect stay for couples.
